Interaction of [Pb(SiPr)2]n with 1.5 equiv. of AgNO3 in DMF under aerobic conditions at room temperature gave a cationic lead-centered thiolate cluster [Pb13(SiPr)6O8](NO3)4 (1). While treatment of [Pb(SiPr)2]n in refluxing DMF in air afforded a two-dimensional layered structure of [Pb14(SiPr)16O6]n (2), comprising of [Pb14(SiPr)18O6]2− units bridged the iPrS− moieties. Molecular structures of the two oxidation products of μ4-oxygen-bridged high-nuclearity lead(II) clusters have been determined by single-crystal X-ray analysis. The UV/Vis properties of the two clusters in both solid state and solution state were also investigated in this paper.
